U-CHANGE Project: a multidimensional consensus on how clinicians, patients and caregivers may approach together the new urothelial cancer scenario.

Introduction: Advanced urothelial carcinoma remains aggressive and very hard to cure, while new treatments will pose a challenge for clinicians and healthcare funding policymakers alike. The U-CHANGE Project aimed to redesign the current model of care for advanced urothelial carcinoma patients to identify limitations ("as is" scenario) and recommend future actions ("to be" scenario).

Methods: Twenty-three subject-matter experts, divided into three groups, analyzed the two scenarios as part of a multidimensional consensus process, developing statements for specific domains of the disease, and a simplified Delphi methodology was used to establish consensus among the experts.

[Leptospirosis and kidneys: a clinical case].

We describe here the case of a young patient, employed in agriculture, who entered the emergency room with fever, headache, hematuria and a worsening of renal function; we diagnosed leptospirosis with renal involvement. As the patient lamented very generic symptoms, the anamnesis was fundamental in leading us to suspect an infection, execute the right laboratory analysis, and correctly diagnose a pathology which is currently very rare in Italy.

Role of autonomic dysfunction in the regulation of myocardial blood flow in systemic sclerosis evaluated by cardiac magnetic resonance.

Aim: Autonomic dysfunction (AD) is an early feature of systemic sclerosis (SSc). A regular endothelial function is a prerequisite for normal response of the myocardial blood flow (MBF) to cold pressure test (CPT). The aim of the study was to evaluate the relation between MBF and AD at rest and after CPT in asymptomatic SSc patients.

Parasympathetic activity increases with digital microvascular damage and vascular endothelial growth factor in systemic sclerosis.

Objectives: The imbalance between angiogenic and angiostatic factors with derangement of the microvasculature are hallmarks of systemic sclerosis (SSc). Raynaud's phenomenon in SSc probably is due to the impaired neuroendothelial control mechanisms between vasoconstriction and vasodilatation. The aim of this study is to evaluate autonomic nervous system function using heart rate variability (HRV) analysis and to correlate with vascular endothelial growth factor (VEGF).

Effects of autonomic dysfunction on exercise tolerance in systemic sclerosis patients without clinical and instrumental evidence of cardiac and pulmonary involvement.

Objectives: Autonomic dysfunction (AD) in systemic sclerosis (SSc) was already confirmed through heart rate variability (HRV) analysis. Cardio-pulmonary exercise testing (CPET) is a useful tool in early detection of exercise tolerance in SSc patients. Aim of the study was to assess the relationships existing between AD and exercise tolerance.

Altered diurnal cardiac sympathovagal balance correlates with nutritional status indexes in systemic sclerosis patients.

Autonomic nervous system is involved in body weight regulation. Gastrointestinal manifestations of systemic sclerosis (SSc) can influence patients’ nutritional status and facilitate the development of protein–energy malnutrition. The aim of the study is to assess the nutritional status of SSc patients and to explore its possible correlation with autonomic dysfunction using heart rate variability (HRV).

Mortality in hospitalized chronic kidney disease patients starting unplanned urgent haemodialysis.

Aim: Data on the outcome of chronic kidney disease (CKD) patients who are hospitalized and start unplanned urgent haemodialysis (HD) are lacking. This prospective, longitudinal, observational study aimed to define the hospital mortality rate and associated factors in CKD patients who start unplanned urgent HD.

Methods: Between January 2003 and December 2009, all patients with CKD who were hospitalized, diagnosed with ESRD and started unplanned urgent haemodialysis at Haemodialysis Service of the Catholic University of Rome, Italy were recruited.

The involvement of T regulatory lymphocytes in a cohort of lupus nephritis patients: a pilot study.

T regulator lymphocytes (Tregs) play a key role in the maintenance of immune tolerance and in the development of autoimmune diseases. Expression of Foxp3 is specific for Tregs, and can be used for the identification of these cells. This study investigated the variations of Tregs Foxp3+ in the kidney biopsies inflammatory infiltrate of different lupus nephritis classes compared to that of ANCA glomerulonephritis, acute tubulointerstitial nephritis and nephroangiosclerosis.

Drugs and Rhabdomyolysis: From Liver to Kidney.

Rhabdomyolysis is a syndrome due to a damage of skeletal muscle and the leakage of intracellular contents into the extracellular fluid and the circulation. Several causes may induce rhabdomyolysis and the major one is the crush syndrome. Most cases of non-traumatic rhabdomyolysis are related to drugs.

Prevalence and clinical features of patients with the cardiorenal syndrome admitted to an internal medicine ward.

Background: Many patients admitted to a Department of Internal Medicine have different degrees of heart and kidney dysfunction. Mortality, morbidity and cost of care greatly increase when cardiac and renal diseases coexist.

Methods: A retrospective cohort study was conducted on 1,087 patients admitted from December 2009 to December 2012 to evaluate the prevalence of the cardiorenal syndrome (CRS) and clinical features.

Rhabdomyolysis after midazolam administration in a cirrhotic patient treated with atorvastatin.

The administration of statins in patients with liver disease is not an absolute contraindication. Hepatotoxicity is a rare and often dose-related event and in the literature there are only a few described cases of fatal rhabdomyolysis in patients with chronic liver disease after statin administration. During treatment with 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, the factors responsible for myopathy may either be related to the patient, or due to interactions with other medications that are metabolic substrates of the same isozymes and therefore able to increase blood statin concentration.

Pathophysiology, diagnosis and clinical management of hepatorenal syndrome: from classic to new drugs.

Advanced cirrhosis is frequently associated with renal dysfunction. Hepatorenal syndrome (HRS) is characterized by the occurrence of kidney injury in cirrhotic patients in the absence of other identifiable causes. HRS is classified in 2 different types.

Nephrotic syndrome and stroke.

The hypercoagulability of patients with nephrotic syndrome could be an important trigger for arterial and venous thrombotic events. Arterial thromboses are less frequent than venous thromboses and the most common locations are femoral arteries. The association of stroke and nephrotic syndrome is extremely rare.

Gabexate mesylate as treatment in the course of ANCA-negative microscopic polyangiitis.

Patients with small vessel vasculitis present fluctuating antineutrophil cytoplasmic antibodies (ANCA) levels to the point that positive ANCA may be missed even if only up to 10% of patients with microscopic polyangiitis (MPA) are ANCA-negative. The first-line treatment of MPA is the association of steroids and cyclophosphamide, especially in the presence of a rapidly progressive glomerulonephritis. Plasmapheresis, intravenous immunoglobulins, and tumor necrosis factor inhibitors have been proposed as alternative to standard therapy.

Hypercoagulability and nephrotic syndrome.

Patients with nephrotic syndrome are at increased risk for thromboembolic events such as deep venous and arterial thrombosis, renal vein thrombosis and pulmonary embolism. This thrombophilic phenomenon has been attributed to a "hypercoagulable" state in which an imbalance between naturally occurring pro-coagulant/pro-thrombotic factors and anti-coagulant/antithrombotic factors promotes in situ thrombosis in deep veins or arteries. Management of thromboembolic events may be divided in prophylactic and therapeutic strategies.

ACTH and azathioprine: antiproteinuric and lipid-lowering effect in the course of idiopathic membranous glomerulonephritis.

Idiopathic membranous glomerulonephritis is a frequent cause of nephrotic syndrome and may have a variable course, from spontaneous remission to progression on renal failure. The therapy is based on alternating steroids and chlorambucil or cyclophosphamide (Ponticelli protocol) for six months. In absence of complete or partial remission after protocol, cyclosporine, adrenocorticotropic hormone, mycophenolate mofetil, rituximab can be used for potential therapy.

Acute renal failure and hypercalcemia as onset in splenic lymphoma.

Hypercalcemia is a rare metabolic disorder in course of B cell lymphoma. The mechanism of hypercalcemia in patients with malignancy may include the increased extrarenal production of vitamin D from tumoral cells or neighboring macrophages, i-PTH or PTHrP from tumoral cells. In this case we reported a 34 years old caucasian woman with acute renal failure and hypercalcemia as onset of splenic lymphoma in absence of abnormal levels of serum vitamin D and PTHrP.

[Malnutrition in patients on chronic hemodialysis: prevalence, pathogenesis, and treatment].

Malnutrition is common in patients on hemodialysis and is a strong predicor of morbidity and mortality. Much progress has been made in recent years in identifying the causes and pathogenesis of malnutrition in hemodialysis patients as well as in recognizing the link between malnutrition and morbidity and mortality. Nevertheless, there is no consensus concerning its management.

Variables associated with reduced dietary intake in hemodialysis patients.

Background: Among the causes of malnutrition in hemodialysis (HD) patients, inadequate dietary intake (IDI) seems to be one of the most frequent and important. Although it has been hypothesized that IDI might be secondary to uremia, anorexia, underlying illness, psychosocial conditions, loss of dentures, depression, aging, or chronic inflammation, definite data on the etiology of IDI in HD patients are still lacking. The goal of this study was to measure the actual dietary energy and protein intakes in stable HD patients and to evaluate which demographic, clinical, dialytic, and humoral variables were associated with a dietary intake lower than recommended by international guidelines.

Anorexia and serum leptin levels in hemodialysis patients.

Background And Aims: Hyperleptinemia is a common feature in hemodialysis (HD) patients. However, the role of increased serum leptin levels in the pathogenesis of HD-related anorexia is still controversial. The purpose of the present prospective study was to ascertain whether hyperleptinemia is causally implicated in the pathogenesis of HD-related anorexia.

Pregnancy during chronic hemodialysis: a single dialysis-unit experience with five cases.

Background: Pregnancy is uncommon in women with end-stage renal disease (ESRD) requiring chronic dialysis. An increasing number of successful pregnancies in women in hemodialytic treatment have been recently reported but few institutions experienced more than one or two cases of pregnancy.

Methods: Between 1988-1998 five pregnancies in patients receiving hemodialysis were observed in our center.
